Very nice. I'm sure there are more than a few of us here that would be interested to see the graphs for comparison, if you are willing to share.

Looks great. The bump down low is odd are you using the IMRC plates? VCT? Very smooth and linear delivery above that. Torque is good, I was at 447/406 before JLT CAI going to take mine to JDM for dyno tune, they expect 490/415 on 93 gas. I would love to see what DI/PI would do on your combo. Did you tune for pump gas or 100+?

The voodoo with just LT headers and E85 makes 520-530 on average. I didn’t dyno mine with the 100 octane tune I gave but on 93 it was 490+. Just south of 500. I need to get her on the rollers with the straight E85R tune and good E85 in the tank.

Car with no gas is 3,344 lbs. I was targeting 3,601 lbs as you get a 0.4 power/weight break.

With where the power finished up I need to be at 3,616 lbs, end of race, so pretty close! Add me, helmet, shoes, gloves, suit, Coolshirt box with ice, and I'll need to finish with 2.6 gallons of gas, or add lead.
